I have two uvc video cameras under one usb port. How could I open them at same time?
I try to get two different uvc_stream_ctrls , and call uvc_start_streaming with these two different ctrls. First is open correctly, but for second, is failed with Busy (-6) error. Since they're using the same interface.
This device works fine on Windows with direct show api. Just do not know how to make it work in libuvc on android.
I also tried with v4l2 driver on android, it also work fine with the v4l2 driver on android with Camera2 api. However, I need to use this device under user space driver on android. Any suggestion on this is appreciated.
The lsusb -t show as follow:
Hello i was able to create 2 camera preview by dividing code in
2 CameraViewInterface and 2 UVCCameraHandler only
So i think you just have to create 2 interfaces one for each CameraHandler.
Mine are behind an usb hub...
